Since EU/ME spec cars valve operation is not "ON" "OFF" like US cars, they have an optional sound kit.. Valves operate in an entirely different manner
No need for the sound kit, I don't run it with my Akrapovic
What about cooling Jackie how are you managing IAT's ?
My car goes up to 65C casually with heat exchangers, aux radiators and methanol :( with a Pure800 on the street
